1.0 Introduction

This Operations Plan addresses landfill operations at South Dunes (that is the former Weyerhaeuser NR Company facility) in North Bend, Oregon (Figures 1 and 2). Weyerhaeuser formerly operated the North Bend Containerboard Packaging Division Mill (mill) at the site. Fort Chicago Holdings U.S. LLC acquired the property in 2012.

Manufacturing operations ceased at the mill on June 30, 2003 and the mill was closed by Weyerhaeuser on August 15, 2003. Weyerhaeuser demolished the mill between August and December 2005. When in operation, the mill facilities included the North Spit (also known as South Dunes) Industrial Solid Waste Landfill (ISWL) and associated wastewater treatment system (WWTS). The ISWL at the now‐closed mill operates under Oregon Department of Environmental Quality (DEQ) Solid Waste Permit Number 1142 and the WWTS operated under National Pollutant Discharge Elimination System (NPDES) Permit 101499. The NPDES permit was updated on January 11, 2013, documenting the change in ownership of the ISWL from

Weyerhaeuser to Fort Chicago Holdings II, U.S. LLC, c/o Jordan Cove Energy, L.P. The current NPDES expiration date is August 31, 2021. Copies of the ISWL and NPDES permits are included in Appendices A and B, respectively. The Solid Waste and NPDES Permits remain active. Environmental monitoring required under the Solid Waste permit is detailed in the facility Environmental Monitoring Plan (EMP; PES, 2012b). The EMP monitoring results are reported annually. NDPES monitoring is reported monthly in a Discharge Monitoring Report (DMR) for ocean outfall and the deflation plain.

This Operations Plan has been prepared consistent with the Solid Waste Permit (Section 7.1) and replaces the existing Operations Plans (Weyerhaeuser, 1997 and PES, 2012). In addition, per Section 10.2 of the permit, the Site Development Plan is incorporated as a section of the Operations Plan. If site conditions, operating status, or site development plans change, the Operations Plan will be updated as needed to address the change(s).

Currently operations are limited to inspections and maintenance of an existing leachate system, stormwater infrastructure, landfill cells, industrial waste pipeline, and Aeration Stabilization Basin (ASB) discharge equipment. Proposed activities are the removal of unsaturated waste, installation of dewatering trenches and drain piping, installation of a well point system, and reestablishing a landfill cover during wet weather months. After wintering, Cell 3 will be clean closed under the terms of a closure permit submitted to DEQ April 20, 2018.

2.0 Site Development

Fort Chicago Holdings II U.S. LLC and its operator Jordan Cove Energy Project L.P. (JCEP) have plans to close the ISWL at the South Dunes site (the former mill areas). Site development for the closure of the ISWL is addressed in the site Conceptual Closure and Post‐Closure Plan (submitted under separate cover). This Operations Plan and the facility’s EMP (PES 2012b) will be revised as warranted upon implementation of Cell 3 closure activities. No new wastes are proposed to be placed in any of the landfill cells.

3.0 General Operations

The South Dunes ISWL has not accepted wastes since December 2005 (except as noted below). The ISWL consists of three landfill Cells (Cells 1, 2, and 3; Figure 2). Cell 1 was capped and closed in 1988 (Tuppan, 2005). Cells 2 and 3 received permitted industrial wastes through the closure of the mill in August 2003. The mill was demolished during August to December 2005. During demolition, Cell 2 received asbestos‐containing debris (transite siding demolition) and Cell 3 received approximately 9,820 tons of general demolition debris. Although unused since 2005, Cells 2 and 3 have not been administratively closed. No wastes have been disposed of at the facility since the completion of demolition activities in December 2005, except where ash amended soils from a pipeline project along the Transpacific Parkway and drill cuttings from on Fort Chicago Holdings II U.S. LLC properties were placed in Cell 3, with pre‐approval from

DEQ. Figure 3 shows the layout of the current ISWL and associated infrastructure. Figure 4 shows the location of ISWL and NPDES Permit related facilities.

3.1 Security

Access to Cell 3is restricted by fencing and locked gates. Public access is prohibited and monitored a minimum of three times per week by JCEP personnel. Security will be maintained, as needed, during closure operations. Whenever there are no personnel performing work, the gates are locked.

3.2 Signs

Signs identifying the facility as private property with no unauthorized access allowed are posted and maintained at appropriate gates and access points to the property.

3.3 Access Hours and Controls

The facility is inactive. No routine access to the facility is allowed. Access to the site must be arranged through JCEP. During closure operations of Cell 3, JCEP will control access and work hours.

3.4 Aesthetics

The site is in a remote location with limited visibility of populated or well‐traveled areas. No specific aesthetic requirements are warranted. JCEP arranges for annual vegetation control to maintain access within the facility and to control the spread of noxious weeds.

3.5 Access Roads

On‐site access roads are maintained as needed to allow JCEP personnel access to the landfill cells, north and south settling basins, JCEP maintained aeration stabilization basin (Figure4) the industrial waste pipeline route and related ISWL infrastructure. Additional access points may be used during Cell 3 closure activities, as needed for truck routing.

3.6 Open Burning

No open burning is allowed at the site.

3.7 Endangered Species

No known endangered species have been identified that are indigenous to the area of the south dunes or ASB. A survey of the South Dunes site for threatened or endangered species has been conducted by JCEP.

3.8 Floodplain Integrity No landfill areas are in an Oregon Special Flood Hazard area (DOGAMI, 2017).

3.9 Sewage Disposal

The site no longer has onsite facilities. Portable sanitary facilities will be provided when closure activities require such provisions.

4.0 Disposal Operations – Waste Handling

The South Dunes ISWL has not accepted wastes since December 2005 except in 2013 where ash amended soils from a pipeline project along the Transpacific Parkway and drilling mud and boiler ash from geo‐technical borings on Fort Chicago Holdings II U.S. LLC properties were placed in Cell 3. The ISWL consists of three landfill Cells (Cell 1, Cell 2, and Cell 3; Figure 2). Cell 1 was capped and closed in 1988 (Tuppan, 2005). Cell 2 and Cell 3 received permitted industrial wastes until the closure of the mill in August 2003. The mill was demolished during August 2005 to December 2005. During demolition, Cell 2 received asbestos‐containing transite siding demolition debris and Cell 3 received approximately 9,820 tons of general demolition debris. Although unused since 2005, Cell 2 and Cell 3 have not been administratively closed, but both cells are maintained in vegetative cover.

The mill facilities included the ISWL and a wastewater treatment system (WWTS). Continued operation of the ISWL has been guided by the DEQ approved Conceptual Closure Plan and Post Closure Plan prepared by PES Environmental, Inc., dated October 26, 2012. Some of the information used in the Conceptual Closure Plan was taken from a report prepared by Thiel Engineering, Technical and Cost Evaluation, Elements of Environmental Closure for the Weyerhaeuser Containerboard Packaging Facility, prepared for the three landfill cells, dated April 2004.

The following is a brief description of wastes stored in each cell of the ISWL:

Cell 1 – This cell was constructed in 1971 and originally received paper, log deck cleanup, salt cake, wire, plastic, and styrofoam. By 1983, salt cake had been eliminated from the waste stream, and paper and other putrescible solids had been reduced. Closure and capping of Cell 1 was performed in 1988 to reduce leachate.

J1-000-CIV-RPT-SHN-00009-00

Landfill Cell 2 was constructed in 1988 and is authorized to receive old corrugated containers (OCC) waste, wire, plastic, fiber, sand, dirt, settling basins solids, construction and demolition debris generated at the site, and miscellaneous cleanup wastes of similar nature. Cell 2 also received asbestos waste from the demolition waste created during mill closure. Cell 2 is still considered open and has some remaining capacity for additional waste before reaching the authorized final grades, although no new waste materials are proposed to be added to Cell 2.

Cell 3—Cell 3 was constructed in 1997. Cell 3 is the only cell completed with a leachate collection system and 60‐mil HDPE liner. Leachate from Cell 3 is collected and piped by gravity drain to the Settling Basins (Figure 3). Cell 3 received the same waste stream described above for Cell 2, sludge from the primary clarifier and ash from the dual‐fuel boiler. Approximately 9,820 tons of mill demolition debris generated during 2005was placed in landfill Cell 3 and covered with sand. Cell 3 also received approximately 40 cubic yards (cy) of construction soils during work on a water line extension performed in 2013 and in March of 2017, approximately 17 cy of drilling mud and boiler ash, along with 22 crushed steel 55‐gallon drums were added to Cell 3.

Landfill Cell 3 surface area covers approximately 5.8‐acres (330 feet by 750 feet), and is defined by a perimeter berm that extends to a height of approximately 5 feet above the existing ground surface. The lined landfill is underlain by a leachate collection system that consists of perforated pipe set in gravel. Leachate collected within the cell drains to the Settling Basins to the east of the landfill. Solid waste in Cell 3 ISWL is estimated to be approximately 40 to 45 feet in thickness at its deepest location. The current appearance of Cell 3 is an elevated area on the eastern portion with varying slope gradients covered in vegetation consisting of low‐lying grasses.

The estimated volume of solid waste in Cell 3 is approximately 176,000 cy. The estimated percentage of each waste stream total volume is presented in Table 1. The volume estimates have been updated from an earlier Cell 3 report (Thiel, 2004), to reflect the addition of construction debris from building demolition in 2005 and waste materials from 2014 and 2017.

Landfill Cell 3 was considered the landfill expansion area and was designated primarily for the disposal of OCC waste, effluent treatment solids, boiler ash, and the 2005 demolition material from the former Weyerhaeuser mill structures. An interim covering consisting of onsite sand was placed over the waste after placement of the demolition debris in 2005.

Cell 3 is underlain by a leachate collection system that consists of a network of perforated pipes surrounded by porous gravel underlain by an impermeable geosynthetic liner. The leachate from Cell 3 drains to two (2) settling basins located just east of the landfill cell. Leachate flows have ranged from approximately 4,300 to 260,000 gallons per day during summer and winter. In recent years, leachate flows have diminished. The wastewater in the settling basins is then pumped to a lagoon and eventually discharged through the permitted ocean outfall. The WWTS discharge is regulated under the NPDES Permit Number 101499.

In the fall of 2014, JCEP and SHN, in cooperation with the DEQ, conducted a pilot waste removal and trucking project to determine if excavation, demolition debris recycling, and off‐site disposal of the waste in Cell 3 was feasible. This pilot project excavated, processed and hauled approximately 2,300 tons of waste. The disturbed areas were subsequently covered with at least 12‐inch of on‐site soils. A summary report of the pilot project results was provided to the DEQ in a letter dated January 9, 2015.

On September 12 and 13th of 2017, a test haul from the North Spit Landfill Cell 3 was performed through a partnership of K&E Excavating and Republic Service’s Coffin Butte Landfill located in Corvallis, Oregon on JCEP’s behalf. The purpose of the test haul was to provide the contractor a hands‐on opportunity to excavate, load, and transport the waste from Cell 3 to Coffin Butte Landfill. The waste was excavated from

two test pits immediately south of the loading platform. The excavated waste consisted primarily of boiler ash, sand, wire, plastic, and ragger tail. No concrete or steel was encountered or excavated. Free water was observed near the bottom of the test pits at a depth of approximately 12‐14 feet from the surface. No wet waste was excavated or loaded. A total of nine truck and trailer loads (252.86 tons) of unsaturated waste were removed from Cell 3. Following the excavation, the area disturbed was capped with an approximate 1 foot of clean sand taken from the borrow area just south of Cell 3. On September 22, 2017, following the placement of the cap, the disturbed areas of Cell 3 and the borrow area were reseeded.

Cell 3 is estimated to contain approximately 176,000 cubic yards (cy) of material, 167,000 cy of waste and 9,000 cy of cover material. However, Cell 3 is only partially filled and includes grades that would not be conducive to a final cover. No substantial quantity of additional waste is expected to be deposited. Without being able to achieve proper final closure grades, and as part of Fort Chicago Holdings II U.S. LLC’s site management strategy to reduce the long‐term environmental risks at the site, Fort Chicago Holdings II U.S. LLC has elected to remove the existing waste from Cell 3 under the waste handling provisions of the existing solid waste permit, and to then remove the entire leachate collection system and liner under the provisions of a DEQ approved Final Closure Plan. A proposed schedule is included in Appendix 6.

Under the Solid Waste Operation Plan, Cell 3 will begin to de‐inventory to the proposed grades shown on Sheet C‐3, Appendix 6. After the dry waste has been removed, dewatering of the saturated waste in the lower portion of the landfill will be initiated and continue over‐winter while the landfill is covered during the

J1-000-CIV-RPT-SHN-00009-00


6

wet season. See Appendix 6, Sheet C‐4 and C‐5 for the dewatering and the temporary cover plans. The remainder of the waste in the cell and the cell floor liner will be removed once clean closure of Cell 3 is initiated, which is anticipated to be permitted for the subsequent year(s). To establish final grades that prevent ponding, an estimated 6,400 cy of fill material will need to be placed in the landfill floor area after the liner is removed. Fill material used to adjust final grades will consist of onsite native soil. Project specifications are included in Appendix 7.

The inventory reduction will be conducted in accordance with a prepared Site‐Specific Health and Safety Plan for on‐site worker protection that includes monitoring and procedures for unanticipated and/or potentially hazardous material encountered during the waste excavation and processing. An additional Health and Safety Transportation plan for loading, handling, and transportation of the waste will also be implemented. This plan will include procedures for accidental spill, containment during on‐site loading and tarping of the trucks, and during transport to the final destination.

The waste removal project is proposed for summer/fall of 2018, and will have a duration of approximately 5‐months. Saturated waste, the liner system and leachate collection layer will be left in place as the dry portion of the Cell 3 contents are removed. Once the waste pile is lowered to Elevation 36 (NAVD) or by October 1, whichever comes first, a dewatering system will be installed and an interim cover placed over the landfill. The remaining waste, interim cover, liner system, and leachate collection layer will then be removed during the Final Closure. The two settling basins will be operated pursuant to the NPDES permit.

Because the facility is closed, does not accept wastes, and the existing landfill cells inactive, the following subsections of the Disposal Operations – Waste Handling section are applicable only to the deinventory of waste:

Weighing Waste loaded on to trucks at the loading station will be weighed at the loading scale. The truck weight and driver data will be recorded and any testing of the waste performed.

Waste Acceptability Procedures Waste loaded from Cell 3 will need to pass a painter filter test to demonstrate that the waste is suitable for disposal at the landfill. No other criteria are applicable to the removal of waste materials. Any restrictions on load sizes will be the responsibility of the contractor and receiving landfill. Liquid Wastes Waste loads not passing the paint filter test will be segregated for further processing on the west section of Cell 3 not in use.

J1-000-CIV-RPT-SHN-00009-00

Salvage

As currently envisioned, the waste will be loaded onto trucks and hauled to a DEQ approved landfill or moved onsite to a processing area or a recycle area. As excavation of Cell 3 contents proceeds, demolition debris will be sorted. Concrete larger than 6‐inch size pieces will be rubblized and the and reinforcing steel removed for recycle. Large metal pieces will be set aside for inspection and recycle or disposed depending on condition. Inspection will be performed by an environmental engineer or environmental geologist. The contractor will process and haul the recycled steel off site in 30 days. The concrete rubble will be stockpiled and left onsite for future use. The concrete stock pile will be retained on site for up to a period of one year. All other waste will be handled as industrial wastes pursuant to the terms of the permit. A conceptual plan showing Cell 3 work areas is included as Figure 3. Salvaged metals will be inspected by the Engineer before being sent to metal recycling yard. Metal will be allowed to accumulate on site for up to 90 days before the recycled material must be removed. The Contractor performing salvage will be required to weigh recycled loads on site and to match the load with the receipt ticket from the recycle yard. Litter Control Windblown litter will be controlled by using a small working face when waste removal operations are occurring. The working face will be covered if removal activities cease for more than a 48‐hour period. Vector Control During the deinventory operations phase waste removal will be controlled by JCEP’s contractor. Removed waste from Cell 3 will be truck loaded, weighed, load balanced, tarped, and inspected prior to leaving the site. Exposure to rodents or birds will be minimized and routinely controlled if required. Wind born material will be controlled by limiting open area. Monitoring of dust will also be required by the site safety plan.

4.1 Leachate System

Cell 3 (Figure 3) has a passive (gravity drain) leachate collection system. No pumps or other mechanical systems are required for operations or maintenance of the leachate collection system. Pumps are required to convey leachate and stormwater from the settling basins through the NPDES permitted discharge systems. The NPDES system has excess capacity and can convey and treat the dewatering liquid sent to the ASB without overflow or upset.

The primary operation and maintenance activities associated with the leachate system are limited to observation of the leachate collection system’s discharge, and include inspecting the system for blockages by observing the discharge into Settling Basin 1. Pumps in the Settling Basin 2 convey accumulated stormwater and leachate to the facility’s ASB (Figure 4). The settling basin discharge to the ASB is located at the northwest corner of the ASB. A second discharge point to the ASB is available in the northeast corner of the basin, which can be used to increase residence time if additional treatment is necessary. In its current configuration, the ASB provides some treatment of the water from the settling basins but primarily it is configured to hold water to maintain flow through the outfall diffusers. During the late summer, the ASB can accumulate a large algae population, which can increase the pH of the effluent. A secondary raw water source has been added to the ASB to add well water from the Coos Bay‐North Bend Water Board (CBNBWD) North Spit Well

J1-000-CIV-RPT-SHN-00009-00


8

Field. The well water helps to buffer the ASB liquid and maintain the pH within permit limits. The need to supplement the ASB with well water occurs during the warmer weather of late summer. During the late summer, JCEP increases ASB monitoring activities to daily inspections. Water from

the ASB discharges by gravity to the facility’s ocean outfall.

The settling basin pumps are checked for proper operation as described in Section 8.0. Discharge from the ASB to the ocean outfall is monitored as a routine inspection. A valve at the ASB outfall connection is adjusted to maintain the ASB level and flow through the ocean outfall to prevent diffuser clogging (Section 8.0). The discharge to the ocean outfall is recorded electronically by a flow meter and water quality tests are performed on ASB samples and reported per the facility’s NPDES Discharge Permit. The ASB outfall is also the NPDES designated water quality sampling point.

4.2 Landfill Gas Control

Landfill gas was monitored from 1998 to 2001 and discontinued with the concurrence of DEQ. No landfill gas monitoring or controls are warranted.

4.3 Surface Water Control

Surface and stormwater management at the facility are covered under Fort Chicago Holdings II U.S. LLC’s NPDES Permit. Because the facility is inactive, no additional surface or stormwater management or control is warranted. Precipitation impacting the landfill surface infiltrates through the landfill waste and is collected on the leachate collection layer as contaminated water. This leachate is discharged into the settling basins located just to the east of Cell 3. Precipitation and the resulting Surface water runoff from the areas surrounding the landfill cell infiltrates into the sandy soils. Subsurface seepage from the settling ponds and from surface water infiltrating into the sandy soils is monitored in accordance with the Environmental Monitoring Plan (EMP). The groundwater quality from this seepage is monitored by the several monitoring wells in the area (LF‐02R, LF‐04A, MW‐16B). Samples of the ground water from these monitoring wells is collected and analyzed for the constituents of concern as described in the EMP.

Immediately following the de‐inventory phase, a temporary cover will be placed over the landfill. The cover will require storm water management which will involve directing surface run off to a 400,000 gallon infiltration basin. The basin has been sized to handle a 10‐year storm. Calculations for determining the basin capacity are attached in Appendix 2.

4.4 Groundwater Control

There are no groundwater controls at Cell 1 or Cell 2, and only Cell 3 is lined. Groundwater monitoring is conducted under the facility’s EMP (PES, 2012b). Annual reports are provided by JCEP (SHN1).

5.0 Disposal Operations – Management of Working Areas

The ISWL consists of three landfill cells. Cell 1 was capped and closed in 1988 (Tuppan, 2005). Cell 2 and Cell 3 have soil caps but have not been administratively closed. Because the South Dunes facility does not accept wastes, and the existing landfill cells are capped with soil, the Disposal Operations – Management of Working Areas section of this report addresses the plan to de‐inventory the waste prior to commencing clean closure. Maintenance of the facility’s closed (Cell 1) and inactive landfill cells (Cell 2 and Cell 3) and facility infrastructure that remained after demolition of the mill is discussed in Section 8.0. During the de‐inventory phase, the working face for waste removal will be covered when waste is not being removed.

Operations at Cell 3 will include the excavation of dry waste materials, loading of the material into trucks, and disposal of the removed waste at a DEQ permitted landfill installing a saturated waste dewatering system and installing a temporary cover. Waste removal operations are tentatively scheduled to begin in June of 2018, and will continue through October 2018. Regardless of the volume of dry waste layer, dewatering will be implemented and the remaining Cell 3 material will be covered with interim temporary cover for the ensuing rainy season.

The first phase of the de‐inventory of Cell 3 will be to remove, segregate, and recycle the landfilled construction debris; remove and transport the waste located in the upper layers of Cell 3to a permitted landfill; and install trench pits and a well point system into the lower layers of the landfill where saturated waste is anticipated to be encountered. If saturated waste is encountered during upper landfill removal activities, work will cease in that area until the leachate has a chance to drain to the leachate collection system. The second phase will be to remove and dispose of the remaining waste, liner, and the leachate collection system as part of the clean closure of Cell 3. In the event construction stops for greater than a 48‐hour period, a daily cover of 6 inches of native sandy material from the borrow area or plastic sheeting will be placed over the working face in general accordance with the solid waste permit.

The lower portion of Cell 3 is anticipated to contain saturated waste. Therefore, Cell 3 will be de‐watered through a series of pits and well points installed in the lower portion of the landfill where saturated waste is likely to be encountered. After the first phase of the de‐inventory operation, the trenches and well points will be installed to allow the landfill to drain. After the de‐watering system is constructed, Cell 3 will be graded to promote positive drainage off of the cell. An interim cover will be placed over Cell 3. The interim

cover will be comprised of 8 mil LLDPE tarps and a grid of sand bags placed over Cell 3 to prevent further precipitation from infiltrating into the cell and to further promote de‐watering of waste in the Cell 3. Cover material will be taken from the borrow area shown on Figure 3. Rain Season Preparation

The operations phase of waste removal from Cell 3 will be hauled by October 1, 2018 or sooner if saturated waste is encountered. In order to complete dewatering over the winter, it will be necessary for Cell 3 to be

J1-000-CIV-RPT-SHN-00009-00

covered to prevent precipitation from impacting the dewatering process. Therefore, the following steps will be taken to ensure Cell 3 is prepared for the ensuing rainy season.

During the de‐inventory process, JCEP’s contractor will assist SHN engineers with conducting exploratory excavations into the lower layers of Cell 3 to determine dewatering properties and finalize the dewatering system design. Beginning October 1, the contractor will install the dewatering system in the saturated waste. The dewatering system will include well point sumps. Some will be excavated and, if possible, extend into the sand layer above the liner. Preparation for the rainy season will also involve grading waste to slope from the center of the landfill to the stormwater management basin cell. The remaining waste will also be covered with 6‐inches of native sandy material followed by an interim cover comprised of an 8 mil LLDPE liner. The liner will be secured using a wind guard cover and a perimeter anchor trench. The cover will prevent precipitation from infiltrating in the landfill while the dewatering system removes excess water. Long‐term post‐closure maintenance will include periodic inspections, repair of vegetation and stormwater controls, and groundwater monitoring.

6.0 Special Waste Management Plan

JCEP does not plan on re‐opening any of the landfill cells for future waste disposal. Based upon these current site operation conditions, a Special Waste Management Plan (SWMP) is not warranted for future special waste handling and disposal. Asbestos‐containing wastes are present in Cell 2. These wastes are managed and protected from exposure and release through inspections and maintenance of the Cell 2 cap as specified in Section 8.0. Proposed activities include clean closure of Cell 3. Therefore, no additional special waste management is warranted.

7.0 Ancillary Operations

As explained in Section 4.0, wastes have not been accepted for disposal at the ISWL since December 2005 (except as discussed in Section 3.0) and JCEP does not plan on accepting any wastes at the site.

7.1 Recycling

During removal of Cell 3 waste, the construction debris will be segregated and recycled as appropriate. Concrete will be segregated, crushed, and stockpiled for beneficial reuse at the facility. Steel debris will be stockpiled for recycling. All other waste materials will be transported to a DEQ approved landfill. Stockpiles will be left on site for a period no longer than one year. 7.2 Truck Washing Tire washing facilities will be implemented during Cell 3 dewatering operations. Wash water will be directed to the existing leachate settling basins.

J1-000-CIV-RPT-SHN-00009-00


11

7.3 Operations Equipment (rolling stock) All rolling stock used during operations will be properly maintained by the contractor performing the work at the contractor’s designated maintenance yard. Only minor equipment maintenance activities will be performed at the construction staging areas as required.

The remaining subsection of this section is Electrical Distribution Systems. Electricity is available at the site and provides power to the Settling Basin pumps that convey water to the facility’s ASB. The ASB discharges under gravity to the ocean outfall. The northwest corner of the ASB has power to the area, but no equipment or power is used. JCEP personnel inspect and maintain the settling basin pumps on a routine basis and during storm events to address electric power outage emergencies and ensure pump operation and prevent overtopping. The inspection and maintenance schedule is outlined in Section 8.0. The facility maintenance checklist is provided in Appendix 5.

8.0 Inspection and Maintenance The following are general descriptions of the intended maintenance items. General items to be inspected and maintained include:

Personal Safety Equipment

Operating Equipment (maintained in designated area only).

Environmental Control Systems (landfill covers, vegetation, leachate/stormwater controls, settling basins and pumps, ASB, IWP, and ocean outfall)

Environmental Monitoring (groundwater monitoring wells, NPDES monitoring)

Transportation System (site roads, access points, and existing infrastructure maintenance)

Inspections during Cell 3 waste removal

Routine inspections for Cells 1 and 2 for erosion issues.

A checklist for routine site inspections, maintenance, and operating activities is provided in Appendix 5.

9.0 Operating Records

Historical operating records for the ISWL are maintained by JCEP and are available upon request. These documents include: inspection records, training procedures, training records, waste volumes and types accepted, financial assurance documents (submitted annually), historical environmental monitoring reports (submitted annually), and, copies of the facility’s permit and plans.

Activities at the ISWL include inspections required by this Operations Plan, waste removal, environmental monitoring and sampling per the EMP and NPDES permit. Records and record keeping requirements for environmental monitoring are described in the EMP and the NPDES permit. Routine inspection records required by this Operations Plan are limited to the checklist described in Section 8.0. These checklists will be maintained by JCEP and will be available for review upon request.

J1-000-CIV-RPT-SHN-00009-00


12

Inspections during Cell 3 removal activities will include documentation of the following

Start up and shut down times Load counts and tonnage for each load, including:

o Outgoing waste load tickets o Recycle load tickets

Personnel and equipment on‐site Appropriate waste manifests for outgoing loads matched to receiving loads Visual inspections for general waste types encountered, Periodic paint filter tests, and Other noteworthy items Dewatering characteristics

o Dry weight o In‐place weight o Grain size distribution

10.0 Contingency The following sections describe actions to be taken at the facility in the event of emergencies.

10.1 On Site Personnel Injuries

There are no permanent, on site personnel stationed at the facility. JCEP personnel and guests are responsible for their personal safety when visiting the site. JCEP personnel will conduct site activities in accordance with standard company safety procedures. JCEP personnel will provide a site‐specific safety briefing to visitors brought to the site. Unauthorized personnel are not allowed on site. In the event of a medical emergency, dial 911.

10.2 Fires and Explosions

The facility has been closed since 2005, therefore, emissions of explosive gas from the landfill is not anticipated. There is, however, a potential for surface fires or explosions from operations. If a fire is observed in the area, emergency services will be notified. The nearest fire station is the North Bay Rural Fire Department fire station located at 67577E Bay Rd, North Bend, OR 97459. 10.3 Fire Prevention

Smoking is prohibited at the site except in designated areas.

10.4 Liner Leak (Cell 3)

A leak in the liner of Cell 3 may not be visually identifiable. Groundwater monitoring at the site is prescribed in the facility’s EMP. Any changes in groundwater quality that may indicate a liner leak or changed site

J1-000-CIV-RPT-SHN-00009-00


13

conditions are reportable to DEQ as specified in the EMP. Following removal of waste from Cell 3, the liner will be removed and properly disposed.

10.5 Leachate Spills

The Cell 3 leachate collection system is designed to gravity‐drain to the north settling basin then flow to the south basin or effluent pump station. The discharge from the leachate collection system is routinely inspected, including the settling basins, the landfill perimeter and neighboring ditches. All Cell 3 leachate related and accessible facilities, such as the discharge weir, exposed pipe, and sampling areas are maintained to prevent blockages of the leachate flow. Based upon the leachate collection and conveyance design, a leachate spill is unlikely.

If a leachate pipe breaks or the leachate drainage ditch/weir is clogged and results in a release of leachate to the ground surface, JCEP will repair the infrastructure that caused the release and attempt to contain and recover the spilled leachate.

10.6 Storms and Inclement Weather

In the event of large, high intensity storms, JCEP personnel perform additional inspection and maintenance site visits to ensure proper operation of the settling basin pumps. After significant storms, an additional inspection is performed to evaluate the condition of the cell caps, leachate conveyance system pumps, and ASB. Any maintenance and repair is performed promptly, as needed, to repair storm‐related damage. 10.7 Notification

SECTION 01 35 29 HEALTH AND SAFETY PART 1 GENERAL 1.01 SECTION INCLUDES

A. This Section includes general requirements for the following: 1. Preparing project Site Specific Health & Safety Plan

2. Implementing project Site Specific Health & Safety Plan

1.02 OTHER

A. The exact nature of materials and wastes disposed of at the SWLs is unknown. The

possibility exists of encountering burn debris, ash, dust and/or other substances during the Work that may be potentially hazardous to the safety and health of personnel, especially those working in the vicinity of open excavations.

B. The burn debris contains metals such as antimony, arsenic, barium, beryllium,

cadmium, copper, lead, mercury, molybdenum, silver, and zinc as well as Aroclor 1254 (a PCB), dioxins, and furans. Volatile organic compounds (VOCs), in particular trichloroethene (TCE), while not contaminants resulting from the burn dump operations, were detected in the groundwater beneath the site. The metals, PCBs, and dioxins/furans associated with the burn debris have a low mobility in soil and are present in the debris. Dispersal by wind is the primary means for migration of these chemicals.

C. Personnel could be exposed to the noted chemicals in the debris and soil through

incidental ingestion, skin contact, and particulate inhalation of wind- and mechanically-eroded dusts. Exposure to VOCs in soil gas is also a potential inhalation pathway. The Contractor is advised of the need for dust control during burn debris excavation, transport and compaction, and earthwork activities.

1.03 SUBMITTALS

A. The Contractor shall submit within 10 days after Notice to Proceed a general Health

and Safety Plan, for review and purposes only. B. Contractor shall submit, after Notice to Proceed, but prior to pre-construction

meeting, a Site Specific Health & Safety Plan to be approved by the Engineer. Acceptance of the plan by Jordan Cove LNG does not release the contractor of liability in the event of an accident or injury, nor does it place any liability on the Engineer.

J1-000-CIV-RPT-SHN-00009-00


C. Sludge has been observed in samples near the bottom of the landfill. D. Saturated waste may be encountered at any level in the landfill but more likely will

be encountered above the leachate collection layers.

1.04 POTENTIAL FOR HAZARDS
